block: virtual-storage: Add dummy driver for Linux v6.11

Browse Source 
The Tegra virtual storage driver fails to build for Linux v6.11 because
of the following issues:

 1. The functions blk_queue_logical_block_size(),
    blk_queue_physical_block_size() and blk_queue_max_discard_sectors()
    have been removed.
 2. The function blk_queue_write_cache() has too many arguments for
    Linux v6.11.
 3. The flag QUEUE_FLAG_NONROT is not defined for Linux v6.11.

Add a dummy driver for this driver for Linux v6.11 until this driver is
fixed.
